AI did not enable anything in this project. According to the readme, it was only used a tiny bit. It would've been possible 100% without AI.
In fact, I had this exact idea on my list of potential future projects for a while so I could teach myself more low-level programming. I avoid AI like the plague in everything I work on, and I still very much considered it doable.
Everything is 100% possible without AI. AI just shifts the effort cost.
